PNEUMATIC CALKlNG-TOOL.

SPECIFICATION forming part of Letters Patent No. 754,175, dated March 8, 1904.

Application filed November 4,1903.

To all whom it may concern:

Be it known that we, JOSEPH JAMES TYNAN and HARRY CLAY MOSTILLER, citizens of the United States, both residing in the city and county of Philadelphia, State of Pennsylvania, have invented a new and useful Improvement in Pneumatic Calking-Tools, of which the following is a specification.

The uncertainty of the results of hand-calking due to the difiiculty of securing skilled labor at the time required and to the personal elements of inattention, variation in the distribution of the tar or pitch filling within the reamed seam, and in strength and direction of blow make it highly desirable to employ a machine for calking purposes. The short time permitted for calking decks, &c., of vessels while they are in port frequently makes this absolutely necessary, if the work is to be done at all. These difficulties require for their correction a calking-machine which is light in weight, rapid and uniform in use, and which is automatic in all of its operations. The device illustrated in the drawings and herein described has been demonstrated to be such a machine, capable in the hands of an unskilled laborer of doing the work of six skilled calkers and with less fatigue to the operator than results from hand-calking.

It is important that the oakum or calking material be uniformly bedded in the base of the out-gage groove-joint, and that consequently the hammer-blows must be uniform, so that the calking will be pressed equally against the symmetric sides, so as to produce an efiicient and reliably tight joint, so that an evenlyreamed seam with a correspondingly equable distribution of evenly-pressed calking material being present it follows that the tar or pitch filling must necessarily be equally distributed along the whole line of jointing, whereby the desired results are attained.

For the purpose of overcoming the above objections to hand-calking we have produced the herein-described novel construction of pneumatic calking-tool, which is readily rendered operative by the pressure of a manuallyoperated trigger of apneumatic tool or ham- Serial No. 179,793. (No model.)

mer of any standard make, such hammer being easily detachable and capable of being relegated to other duties in a few moments when the calking-tool is not being used.

The invention also consists of novel means for eliminating the jar or shock usually incident to the operation of pneumatic tools, whereby a single operator is enabled by this machine to easily perform the work of from six to eight expert hand-calkers, and yet with this extraordinary increase of output his duties, from the standpoint of fatigue, arefifty per cent. lighter than the work of one hand calker.

Our invention consists of arnovel construction and manner of supporting the taper disk employed, which is adapted to perform its desired function automatically and accurately.

It also consists inthe provision of novel devices whereby the blows of the reciprocating hammer or piston of the detachable pneumatic tool are not struck upon the rollers of the frame or carriage which constitutes the calking apparatus; but said blows are received by the disk-bearing alone, thus saving the decks from being pounded or injured.

It also consists in novel means for automatically feeding the oakum or other material from a spool to the under side of the taper disk or calking device, and thus automatically feeding said material into the outgage-joints.

It also consists in the provision of novel means for enabling the entire apparatus to be automatically propelled, which is accomplished by so inclining the hammer as to allow the resultant energy caused by its vibration to drive the taper disk or calking device along the groove to be calked with a simultaneously equal movement of the carriage or rollerguide.

It further consists of a novel construction of depth-regulator, whereby the detachable pneumatic hammer or other tool may be locked at any desired position, whereby the possible working depth of the calking device may be conseqently increased or decreased, according to requirements.

It further consists of other novel features of construction, all as will be hereinafter fully set forth, and particularly pointed out in the claims.

Figure 1 represents a perspective view of a pneumatic calking-tool embodying our invention. Fig. 2 represents a side elevation of Fig. 1, showing a part of the hammering and cushioning devices in section. Fig. 3 represents a front elevation of Fig. 1, certain parts being removed for clearness of illustration. Fig. 4 represents a sectional view, partly in elevation, showing the hammering and cushioning devices and the means for locking the calking devices at the desired inclination. Fig. 5 represents a perspective view of the coupling employed for detachably securing the pneumatic hammer in position. Fig. 6 represents a perspective view of the fork or anvil which carries the calking device.

Similar numerals of reference indicate corresponding parts in the figures.

Referring to the drawings, 1 designates the cylinder or barrel of a pneumatic hammeringtool having a long or short stroke and constructed in accordance with any of the wellknown types, said tool having a grasping-handle 2 and a manually-operated throttle-valve trigger 3 therein, which controls the admission of compressed air or other motive fluid from the hose 4 to the cylinder 1.

5 designates a split coupling which surrounds the front end or nose-piece 6 of the cylinder 1, said coupling having an internal shoulder 7, adapted to engage the contiguous portion of the hammer-cylinder 1, while its forward portion 8 is threaded for engagement with the cylinder 9.

1O designates trunnions attached to the cylinder 9, said trunnions having their bearings in the sides 11 of the framework or carriage 12, which has the projecting legs 13 and 14, the rear legs 13 supporting the rollers 15, while the forward legs 14 support the rollers 16.

17 designates a reel which is supported in suitable arms 18, mounted upon the carriage- 12, said reel having wound thereon the oakum or other calking material 19, the latter being threaded from the reel through the needle or guide 20, the latter consisting of a troughshaped member having the base 21 and the sides 22, which terminate at the lower portion in the cylindrical guide 23, through which the oakum passes, as indicated at 24, the oakum being shown in Figs. 1 and 2 as being pressed into the seam 25 by means of the rotary calking device or disk 26. The rotary device or calking-tool comprises in the present instance a disk having its walls converging from the center outwardly and is mounted in the arms 27 of the forked anvil, composed of the body portion 28 and the head or flange 29, said body portion passing through an opening in the lower portion of the cylinder 9 and having the nut 30 screwed thereon, against which abuts one end of the spring 31,

the other end of said spring abutting against the shoulder 32.

33 designates a shank or bolt which is adapted to be loosely inserted in the body portion 28 and which when the, parts are assembled projects into the nose-piece 6 of the pneu matic impact-tool, whereby it will be seen that said shank 33 is adapted to be struck by the reciprocating piston 34 of the pneumatic impact-tool, which may be constructed after any usual or approved manner. It will thus be clear from the foregoing that the tension of the spring 31, having its ends abutting against the nut 30 and the shoulder 32, will normally hold the parts in the position seen in Figs. 2 and 4, it being apparent that the impact of the hammering piston 34 upon the shank 33 will be imparted to the anvil, consisting of the arms 27, the flange 29, and the body 28, said spring serving to return the parts to the position seen in said Figs. 2 and 4 after the impact of the'blows of the hammering piston 34, so that the operation of the device is cushioned and the vibrations will be reduced to a minimum or entirely obviated and fatigue to the operator will be practically overcome.

It is in practice sometimes necessary to vary the angle of inclination of the pneumatic impact-tool and the calking apparatus from the position seen-in Figs. 1, 2, and 4, and to provide for this we have placed upon one of the sides 11 of the supporting-carriage a bracket 35, having a recess 36 therein, in which is contained the stem 37, having the finger-piece 38, said stem having a head 39 and terminating in the end portion 40, the last-mentioned parts constituting a latch-pin which is adapted to enter one of the holes, as 42, in the side of the cylinder 9. The end of the stem 37 is normally held in the desired position by means of the spring 43, so that it will be seen that upon pulling the latch-pin outwardly the i11- clination of the cylinder 9, and consequently of the calking-tool and its adjuncts, may be varied, according to requirements. In order to prevent improper rotation of the fork in which the calking-tool 26 is carried, we provide a recess 44 in the head 29, into which enters the stop 45, the latter being of angular shape, as will be understood from Fig. 2, and adapted to engage said recess, whereby the rotary calking device and its adjuncts are prevented from turning or being in improper alinement.

The operation is as follows: The parts being assembled in themanner indicated in Figs. 1 and 2 and the oakum 24 having been started in the joint or seam to be calked the rotary calking tool or disk 26 is placed in the position indicated in Figs. 1 and 2. The operator grasps the handle 2 and depresses the manually-operated finger or thumb piece 3, whereupon admission of the motive fluid is permitted and the reciprocations of the piston 34 begin, and the impact thereof being transmitted to the shank 33 will be also transmitted to the forked anvil and the rotary calking device 26, which latter is so "correlated to the other parts of the apparatus that it simultaneously performs a dual function, to wit: The oakum is hammered into the seam and simultaneously with this hammering action a rotary motion is imparted to the calking-disk, so that the machine automatically advances without requiring the application of force to any extent to the handle 2 to propel it. When it is desired to change the inclination of the calking apparatus, the same can be readily done by means of the latch-pin or its equivalent, and when it is desired to use the pneumatic impact-tool for other purposes the same can be readily disengaged by unscrewing the coupling 5, as is evident.

Our present invention is distinguished from calking devices wherein the hammering piston reciprocates in a vertical line and wherein the calking device consists of a verticallymoving tool which does not rotate, since in our invention the pneumatic hammer or impact-tool is inclined, and its blows are imparted to the calking device in such a manner that the latter is caused to rotate and by its rotation draws the oakum from its reel to the desired extent and also effects the propulsion of the entire apparatus.

It is possible by the use of our invention to procure an evenly-reamed seam with a correspondingly equable distribution of evenlypressed calking material, and it consequently follows that the tar or pitch filling must necessarily be equally distributed along the whole line of jointing, thus obviously obtaining a most desirable end in a manner much more rapid, efficient, and expeditious than has been heretofore possible or even hoped for with the present method of hand-calking.

We also desire to lay special emphasis upon the novel manner whereby the hammer is guided and supported in its adjustable position, as well as the novel provision for advantageously transmitting the blow of the reciprocating piston to the desired point without any injury to the decks.

It will be apparent that slight changes may be madeby those skilled in the art in the calking-tool and in the manner of constructing the carriage and assembling the various parts which will come within the scope of our invention, and we therefore reserve to ourselves the right to make all such changes as come device, a support for said tool and device and means for detachably connecting said impacttool with said support.
